The lesson on chakra theory

boruto ,Sarada and chocho had all made it to the academy on time thankfully, as they all took their seats the door had opened and it wasn't shino but Tsunade! " hello class I'm ex hokage Tsunade and I'm going to teach you about Chakara size theory!" Tsunade said proudly as his tits jiggled as she talked.

boruto and the other boys could only stare at her massive breast, now boruto has seen some big ones before, his own mom had some nice tits! but Tsunade was on a whole other level, " now can anyone tell me about Chakara size theory? " Tsunade asked the class

Sarada raises her hand, " the theory is the more Chakara you have the bigger your ahem 'parts' will be " Sarada said blushing hard since it was kind of embarrassing, " that is correct! now you all are still growing so most of you will grow into sexy ninja! like myself " Tsunade flaunts groping her breast, every boy in that room had a hard erection sadly fapping in class is not allowed.

" Now this theory started couple years ago when the 7th hokage was your age, after we were able to get a closer at his Chakara, we saw it was affecting his penis size growth, and for his age that boy was a monster! you should have seen him go ham on Sakura's bubble butt!" Tsunade said remembering the sight of Naruto fucking Sakura senseless, both boruto and Sarada blush in embarrassment of their parents fucking each other, " Haha anyway let's go onto the next question, what happens when someone has less Chakara than others? " Tsunade look around the class for hands

" they have smaller dicks, can range from a inch shorter to a baby dick" chocho said casually eating chips, boruto tenses and covers his crotch subconsciously, he did not want anyone to know his little secret, " correct chocho! now we have a video showing the effects of so much chakra, boruto and sarada if you do not want to see your parents fucking one another i do recommend looking away but it does show us the effects of this phenomenon " Tsunade warns as the lights dim and the projector starts to play
